 In his Explorer Series talk, NCAR scientist Dr. James Dome discusses a new era of extreme weather impacts. I'm driven to understand how extreme weather works, how we can predict it. I'm going to review what we know about extreme weather, how we know it, and then also how we conduct science in collaboration with non-scientists. Climate change is a hot topic in the insurance world. I work with the insurance industry to better enable society to face this changing risk of extreme weather. So I think one of the main take-home messages is that climate change is not something we're waiting for. A portion of it has actually already happened.
